Tammy Mercer

Is Tammy trying to become the most hated woman in America? What happened that changed her personality? Or has she always been so obnoxious, demanding, entitled, narcissistic and mean to Amy? If I were Amy, I'd move ASAP and let the chips fall. Tammy appreciates NOTHING that Amy (or anyone) does for her. She seems like a different person. So, the question is 'Was last season the real Tammy? Or is this the real Tammy? When she said someone wouldn't regret it if they break through her walls, it felt like she was advertising. There is something way different about her and I DO NOT like her!!
